  5. EU Unification: the institutions Best in theory – poor in practice a (complicated) market example • monetary policy, currency, eurozone • European Single Market • fiscal policy FORTHCOMING

  6. EU Unification: the technology Linked Data or Web of data • “publish once, use many times”. • different consumers extract different slices of the data for different purposes • publish in context: value & “meaning”

  7. EU Unification: the technology • Linked Data (LD) + Open Data =LOD • Economic LOD as “data currency”

  8. Why LOD? • Transparency & innovation Network effects: enabling users to • bidirectional & massively processable interconnections among data • re-using the existing infrastructure in the government and business spheres

  11. Economic LOD: use cases • Business applications on top • Users: citizens, gov., EU, business • track the life-cycle of every financial flow: evaluate budget allocation, tenders, spending and their efficiency • pre-allocate resources on provisional public works • receive & submit information in real-time

  12. Economic LOD:engineering

  13. Government Budget • heterogeneous repositories & methods (mainly PDF)

  14. Tenders • Closed data in HTML • Public Contracts Ontology (PCO), e.g. • pco:Contract and pco:AwardCriterion • Common Procurement Vocubulary • now working on linking our ontology to: • Payments Ontology • GoodRelations • FOAF

  15. Spending • most dynamic & open part • increasing number of countries/cities • raw & structured data • leader: the Greek Clarity project • spending decisions ex-ante to execution • Actually every decision

  16. www.publicspending.gr (*****) • based on Greek Clarity & Tax information • semantify, interconnect, clean, visualize, SPARQL endpoint, daily update • PSGR ontology Links to • WESO products classif. • UK Payments Ontology • DBpediaand Geonames • …more to come

  17. Business Information • Registries: mainly closed • Key standards • Classification of Products by Activity (CPA) • eXtensible Business Reporting Language (XBRL)
